About SBID Interior Design Contracts

When the UK left the EU, the restriction that prevented SBID (as the UK representative for interior design to Europe) from providing members with a client contract (Letter of Appointment) dissolved.

To address the most requested member benefit, SBID seized the opportunity and partnered with the leading contract provider for government and commercial procurement contracts across the design and construction industries.

In 2021 SBID uniquely launched the three interior design service contracts to support its diverse professional membership network and address differing levels of project complexity and service skills.


The contracts are used by most trades and professions in property and construction industries, adding additional comfort for the client and all appointed trades on commercial projects.


The pioneering suite of contracts serve to protect SBID Members and their clients from conflict, whilst providing the ability for amendments throughout project procurement.
